Bug Description

Previously using nvidia-367 with Ubuntu 14.04. Now Ubuntu 16.04 with
nvidia-367.57-0ubuntu0.16.04.1

After upgrade two problems have occurred.
1) Splash screen at startup that prompts for LUKS passphrase has really low resolution and does not accept input to decrypt the filesystem. Booting is currently only possible with the 'nomodeset' option.
Kernel version does not affect this.
This affects at least
* nvidia-367.57
* nvidia-375.26 (from PPA)
Older version nvidia-340.101 is NOT affected.

2) When booting with two monitors & extended desktop the computer will go to suspend mode. Sometimes it will go into suspend repeatedly.
This happens 'most of the time' when the laptops lid is closed and with all driver versions. Probably unrelated to graphics driver.
